The Mack CHU 2013 and newer four post Grizzly Moose Bumper is a heavy-duty, industry-proven bumper designed to fit most Mack CHU models from 2013 and newer. It features a polished mirror-like finish, high-strength boxed vertical uprights with 3-inch OD cross tubes, and quad hinge bushing technology to eliminate pivot wear. The bumper also includes a heavy-duty center tow pin that doubles as a safety latch, a urethane anti-rattle system to eliminate vibration and rattling, and an extruded header bar that complements the truck's profile. This durable bumper is practical, reliable, and built to last.
